Built-in load bulb helps verify circuit integrity and quickly identify weak connections, voltage drops, and wiring faults during troubleshooting.
Audible and Visual Safety Alerts
Audible and visual alerts provide immediate feedback for conditions such as high voltage, overheating, and reverse polarity. A power-on tone also helps confirm circuit continuity without constant screen monitoring
Interchangeable Probe Connections
Standard 4mm banana jacks allow quick switching between clips and probes for different testing needs. The heavy-duty alligator clip is built for durability and consistent performance during repeated use
High-Accuracy Voltage Measurement
Provides ±0.1V accuracy from 3.3–60V and ±0.2V from 60–65V with a real-time digital display for clear, reliable voltage readings during diagnostics.
Intelligent Polarity Identification
Dual-color backlighting clearly indicates positive and negative polarity, with on-screen ± indicators that help prevent reverse connections and support safe, confident testing.
Extra-Long Cable for Flexible Testing
The 12.5-foot cable provides greater reach when working around vehicles.
BREXIT 2021 EUROPEAN TAXATION CHANGES:
For European Customers prices now displayed in cart once you enter your address will have 20% UK VAT Tax removed, however you will have to pay some form of Duties / VAT prior to delivery of your goods. If you are unsure of charges we recommend you should contact your local authorities ahead of placing your order.
Do we ship abroad ?Yes we do, to almost anywhere in the world though remember the postage is often high when shipping anything bulky. Most bulky items we export will go by UPS so you can track the package online and could reach America within 48 hours providing its in stock !
However there are a few countries we do not ship to, some of these include: Thailand, Malaysia, Indonesia, Russia, Nigeria, Macedonia, Syria, Ukraine, Lebanon.
Why is postage on bulky items to some countries expensive compared to some other companies ?For both yours and our safety we use well known couriers such as DPD Local and UPS for shipping, then we know exactly where it is in the world at any time and we know its going to arrive safely. Shipping small items can be cheap, but items such as bodykits are expensive to ship - we have a very small margin on the postage fees merely to cover packaging. We can now ship using standard post on some items, however using all methods you may incur import charges when you receive the goods for which we cant be responsible for.
